@halloweenchild13; Yes, some of the puzzles do require that your Companions "Hold Position" in order to activate certain items. And it's a royal PitA to have to keep issuing that order to the rest of the Party when your running around with the one you're controlling... But it does work, and it allows you to complete the "Dead Hand" puzzle. (I assume that's the one you're talking about.) I've done it that way about a dozen times. Never like it, but always get through it. 🤒
[EDIT: There will be no further "patches" to DAI, so no sense in continuing to whinge about this issue. Simply employ the workarounds and get past it.]
